Computer is a versatile device that you can use to do many things. You can do such office activities as writing documents, creating spreadsheets, making presentations, and doing calculation conveniently using computer. You can also use your computer for shopping, working, updating your knowledge, and doing many other activities that make your life seem very lively. Computer is also a great device to get you and your whole family entertained. Computer has long been frequently used to play games, music, picture slideshow, and videos. The role of computer in facilitating human life becomes very significant when it is equipped with internet, which allows millions of people from different parts of the world to share stories, pictures, videos, and many other items that are beneficial for them.

However, in spite of a huge role played by computer in facilitating human life, computer can also cause serious danger that sometimes can be very devastating. In addition to being a device that stores many beneficial things, computer is also a device that is everlastingly threatened by malwares. Those malwares may emerge as viruses, which attack your computer to reside there and to copy themselves; spywares, which attack a computer to steal its users’ personal data; Trojan horses, a kind of virus whose purpose of attacking a computer is to make its system environment altered and even damaged; and worms, which attack a computer in order to interfere with the host computer’s operation. Most of the time, the attack launched by those malwares can cause such devastating effects as computer system malfunction, data loss or deletion, and unauthorized access and theft of personal and confidential information.

In order to prevent your computer from all of those adverse effects, you have to protect your computer using a reliable Antivirus program. This program is available for download from the internet and for purchase from any computer stores in your locality.
